The constructors for the :class:`qiskit.quantum_info.Statevector` and
|
|
:class:`qiskit.quantum_info.DensityMatrix` classes can now take a
|
|
:class:`~qiskit.circuit.QuantumCircuit` object in to build a
|
|
:class:`~qiskit.quantum_info.Statevector` and
|
|
:class:`~qiskit.quantum_info.DensityMatrix` object from that circuit,
|
|
assuming that the qubits are initialized in :math:`|0\rangle`. For example:
|
|
|
|
.. jupyter-execute::
|
|
|
|
from qiskit import QuantumCircuit
|
|
from qiskit.quantum_info import Statevector
|
|
|
|
qc = QuantumCircuit(2)
|
|
qc.h(0)
|
|
qc.cx(0, 1)
|
|
|
|
statevector = Statevector(qc)
|
|
statevector.draw(output='latex')
